Shares of

Select Comfort

(SCSS)

were among the

Nasdaq's

losers Thursday, tumbling 18% after the mattress maker cut its full-year earnings forecast amid disappointing sales.

The company expects 2006 earnings of 80 cents to 87 cents a share, below its previous view of 95 cents to 97 cents a share. Analysts polled by Thomson First Call project earnings of 96 cents a share. The company blamed the shortfall on lower-than-expected fourth-quarter sales. "This quarter's sales have been disappointing, as we've noted a closer correlation in our business with housing industry trends," Select Comfort said. Shares were trading down $3.78 to $17.21.

Zoltek

(ZOLT)

slid 7% after a jury said the carbon-fiber maker would have to pay damages of $36 million for breaching obligations under a supply agreement. Zoltek said it believes it has strong legal grounds to overturn the verdict. Shares were down $1.74 to $22.50.

Shares of

Finish Line

(FINL)

rose 6% after the athletic-wear retailer previewed a smaller-than-expected third-quarter loss. For the quarter ended Nov. 25, the company expects to report a loss of 6 cents to 8 cents a share. Analysts, on average, had forecast a loss of 9 cents a share.

Meanwhile, Finish Line posted sales of $281.5 million for the period, with a same-store sales decline of 3.3%. Analysts projected sales of $279.6 million. Shares were adding 76 cents to $13.79.

Shares of

DSW

(DSW) - Get Report

jumped 13% after the shoe retailer's third-quarter results handily beat expectations. The company earned $16 million, or 36 cents a share, up from $10.9 million, or 25 cents a share, a year ago. Analysts projected earnings of 27 cents a share. Same-store sales rose 2.6% from the year-ago period, and revenue rose to $332.2 million from $302.2 million.

For the full year, DSW raised its earnings forecast to a range of $1.35 to $1.38 a share from its previous guidance of $1.24 to $1.27 a share. The stock recently changed hands at $37.96, up $4.25.

Bebe Stores

(BEBE)

slumped 10% after the retailer's November same-store sales data disappointed investors. Same-store sales for the four-week period ended Nov. 25 increased 5.8% but missed Wall Street's estimate for 7.4% growth.

"The first three weeks of November were below our expectations, but this was offset by a very strong customer response to our week-four and Black Friday offering," the company said. Bebe said that if December results are similar to November results, second-quarter results would be at the low end of its previous guidance. Shares were trading down $2.11 to $19.98.

Shares of

Christopher & Banks

(CBK) - Get Report

fell 9% after the women's clothing retailer posted a steeper-than-expected same-store sales decline for November. Same-store sales fell 8%, compared with Wall Street's expectation of a 1.6% drop. The company also posted third-quarter sales of $139.3 million, short of analysts' forecast of $146.9 million.

"Unfortunately, we did not experience improved sales results in November," Christopher & Banks said. "We believe our overall holiday assortment evolved more quickly than our core customer was willing to accept." The company expects to reports third-quarter earnings of 24 cents to 25 cents a share. Analysts project earnings of 25 cents a share. Shares were down $1.80 to $18.53.
